Many open source projects have moved to using SPDX identifiers
to specify license information, reducing the amount of
boilerplate code in every source file. This patch replaces
the bulk of SPDK .c, .cpp and Makefiles with the BSD-3-Clause
identifier.
Almost all of these files share the exact same license text,
and this patch only modifies the files that contain the
most common license text. There can be slight variations
because the third clause contains company names - most say
"Intel Corporation", but there are instances for Nvidia,
Samsung, Eideticom and even "the copyright holder".
Used a bash script to automate replacement of the license text
with SPDX identifier which is checked into scripts/spdx.sh.

spdk_bit_pool is a wrapper around spdk_bit_array with the
intentions of providing much better performance for allocating
from a fragmented bit array. The cost of searching a large bit
array for a cleared bit can become expensive so the spdk_bit_pool
will provide an ability to track extents of recently cleared
bits.
This initial commit does not adding the tracking yet - it is strictly
a wrapper around spdk_bit_array with enough functionality to replace
the use of spdk_bit_pool in SPDK blobstore with equivalent performance.
This will allow us to switch blobstore to use this minimal
wrapper first, and then iteratively improve spdk_bit_pool to provide
the better performance.

spdk_bit_array_find_first_set() returns UINT32_MAX if no
set bits are found. But spdk_bit_array_find_first_clear()
would return the size of the bit array instead in this case.
(Note: the comments say size of the bit array + 1 which was
incorrect)
So this patch makes spdk_bit_array_find_first_clear()
consistent with spdk_bit_array_find_first_set() and returns
UINT32_MAX if no cleared bit is found.

The out-of-bounds case in the bit array accessors should not happen
normally, so help the compiler order the basic blocks correctly so that
the in-bounds case is the fallthrough path.
